Add the dry ingredients (almond flour, protein powder, tapioca flour, coconut sugar, baking soda, and salt) to a medium-sized mixing bowl. Whisk until just combined.
Add the wet ingredients (cashew butter, vanilla extract, and maple syrup) to the dry ingredients and mix well until there are no lumps remaining.
Roll your dough into about 12 cookies and place them on a parchment or silicone-lined baking sheet.
Pop your cookies in the oven for 13-15 minutes.
Remove from oven and top with flaky sea salt - be generous!
